DETACHABLE BUTTON.

SPECIFICATION forming part of Letters Patent No. 250,130, dated November 29, 1881.

Application filed September 7, 1881. (No model.) I

To all whom it may concern:

Be it known that I, JAMEs O. BLAKE, of Warren, countyot' Bristol, and State of Rhode Island, have invented a new and useful Im- 5 provement in Detachable Buttons; and I do hereby declare that the following specification, taken in connection with the accompanying drawings, forming a part of the same, is afull, clear, and exact description thereof.

My invention relates particularly to that class of buttons in which the shoe is hinged to the post, so that it can be turned from a position parallel with the button-head to a position parallel, or nearly so, with the post.

My improvement consists in providing the shoe of the button with a plate having ears which project above the surface of the plate and cover the ends of the pin member of the hinge, so as to prevent said pin from becoming 2o accidentally displaced.

Referring to the drawings, Figure l represents, in partial section, a button embodying my improvement. Fig. 2 shows, in perspective, the post, the hinge member of the shoe,

2 5 and the eared plate detached from each other and also combined.

A is the button-head, to which the postB is attached, the said post having an enlarged end, I), which forms its pivotal member.

is the shoe, which is composed of a shell, 0, and a centrally-perforateddisk, D, secured thereto, the said disk having lugs d d, which form the pivotal members of the shoe.

E is the pivotal pin, which passes through 5 the lugs d d and thepost end I) and hinges the shoe to the post.

Fis a leaf-spring, (shown in section in Fig.1,) which bears upon the disk I) and engages the post end I), so as to retain the shoe in a position parallel with the button-head, and also parallel, or nearly so, with the post when the shoe is turned, in order that the button may be applied or removed.

G is a plate secured to the shoe by solder, or in any preferred manner, as by turning the shell 0 over upon it, as shown in Fig.1. The plate G is centrally perforated, and is pro- .vided with ears 9 g, which project above its surface and cover the ends of the pin E,thereby concealing the same, as shown in Fig. 1, and preventing said pin from being accidentally displaced.

By the use of my improvement upon a button the shoe is securely retained against loss. It also presents a more finished appearance,as the ends ofthe pivotal pin, as well as the spring, are concealed from view.

Should the removal of the pin become necessary or desirable, the ears 9 9 may be turned down and the pin beremoved without damage to the article.

What I claim as my invention, and desire to secure by Letters Patent, is- Y As an improved article of manufacture, a detachable button composed of a head, an attached post'having an enlarged free end, a shoe provided with a disk, I), having pivotal members (I (I, a pivotal pin passing through the members d d and through theenlarged post end, a spring bearing upon the disk I) and engaging the post end,and a plate, Gr, se-

cured to the shoe and having ears 9 g, which cover the ends of the pivotal pin, substantially as and for the purposes specified.
